Principles of Wave Propagation, Sound, and Light Physics

NDAS OR it is a propagation of a disturbance of some property of a medium that propagates through space carrying energy. Types of Waves: Depending on the dimensions of the spread: 1) one-dimensional: the wave propagates in one direction. 2) Dimensional: The wave propagates in a flat surface. 3) Three-dimensional: The wave propagates in the 3 directions. According to the type of media in propagating k: 1) O. Mechanical: nez a material medium to propagate. Ex: sound. O. Electromagnetic: spread vacio.Ej also in: light. According to the k direction in the particles of the medium vibrate in relation to the direction of wave propagation. 1) O. Longitudinal:The particles of the medium vibrate in the same direction in the k disturbance progresses. 2) O. Transverse particle of the medium vibrate in a direction perpendicular to the advance of the disturbance. Magnitudes k characterizing a wave: amplitude (A): maximum value k na particle moves through his position EKILIBRIO minetras vibrates. M Wavelength (/): minimum distance between 2 points k are in the same state of vibracion.M Period (T): time k takes a middle point in completing a vibration. S Frequency (f, v): Number of vibrations produced in a k V.De seg.Hz. Propagation (v): distance k progresses tiempo.M wave per unit / s. SOUND: E-shaped caused by the vibration of a field k is spread by mechanical wave is a longitudinal wave and three-dimensional.For k there is a sound: 1) Focus sound, the body vibrates. 2) Half elastic material, for k particles of the medium vibrate and can propagate the wave. 3) receiver capable of capturing and interpreting the sound wave. How it spreads sound?: It spreads when the particles of the medium vibrate and transmit their vibrations to sound vecinas.La V depends on the medium and the second to the k T is: 1) It is greater when more dense the higher medio.Es in solids and lower in gases.2 lso) is greater the larger the T th and increases VV = 340m / s. LIGHT: E-shaped bodies emitted x k x allows us to perceive through the sense of light vista.La in a transverse wave in the air porpaga to 3x10 ⁸m / s. Refractive index: ratio between the V of light in the vaio and the V in that medium. (Transparent, Opaque, Translucent).How is light porpaga?: In a homogeneous medium, light travels in straight lines. Laws of reflection: 1) indicencias ray, the reflected beam and the normal are on the same plano.2) The angle of incidence is the angle reflesion =: î = ^ r.Ej: Kaleidoscope. laws of refraction: 1) The incident ray, refracted ray and the normal are on the same plano.2) The angle of incidence and refraction are related by Snell's law. Dispersion: is the separation of 1 k radiation formed by the effect of refraction. spectrum: analysis of the various simple radiation comprises radiation k k we get a sample prepresentacion cuerpo.Su the E and the intensity of these radiations. electromagnetic spectrum: conunto of all electromagnetic radiation k exist.
